17. The nurse is caring for a patient who has taken an overdose of aspirin several hours prior.
The provider orders sodium bicarbonate to be given. The nurse understands that this drug is
given for which purpose?
a. To counter the toxic effects of the aspirin
b. To decrease the half-life of the aspirin
T
c. To increase the excretion of the aspirin O
d. To neutralize the acid of the aspirin
ANS: C
Aspirin is a weak acid and is more readily excreted in alkaline urine. Sodium bicarbonate
N
alkalizes the urine. It does not act as an antidote to aspirin, decrease the half-life, or neutralize
its pH.

18. The nurse is preparing to administer a drug that is eliminated through the kidneys. The
nurse reviews the patients chart and notes that the patient has increased serum creatinine and
blood urea nitrogen (BUN). The nurse will perform which action?
a. Administer the drug as ordered.
b. Anticipate a shorter than usual half-life of the drug.
c. Expect decreased drug effects when the drug is given.
d. Notify the provider and discuss giving a lower dose.
ANS: D
Increased creatinine and BUN indicate decreased renal function so a drug that is eliminated
through the kidneys can become toxic. The nurse should discuss a lower dose with the provider.
The drug will have a longer half-life and will exhibit increased effects with decreased renal
function.

d. Nonspecific drugs require higher doses than specific drugs to be effective.P
ANS: D
Nonspecific drugs can act on one type of receptor but in different body tissues, or a variety of
receptor types, or act on hormones to produce effects. Nonspecific drugs do not require higher
